Answer:
volume is 1570 cm³
mass is 12560 g
Step-by-step explanation:
1m = 100 cm
the volume is :
1/4 x 
x 6² x 100 - 1/4 x x 4² x 100
= 900 - 400 { v = 1/4 d²h }
= 500
= 500 x 3.14
= 1570 cm³
the mass of the pipe is:
1570 x 8 = 12560 grams
Answer:
b = 19 inches
h = 5 inches
A = 95 inches^2
Step-by-step explanation:
The area is given by
A = bh where b is the base and h is the height
b = 19 inches
h = 5 inches
A = 19 inches * 5 inches = 95 inches^2
so for this equation, I would do 7/8 = 72/x
1 72
- = -
8 x
Cross multiply to get 72 * 8 = 1x
solve for X 576 = x
